It is demonstrated that the calibration method using a standard pyrheliometer and a shaded pyranometer is better than using only one standard pyrheliometer; and the iteration method for determining the calibration factor of spectral pyranometer is presented.
论证了以一台直接日射表和一台遮蔽的总日射表为标准的校准方法优于仅用一台直接日射表为标准的校准方法,并提出了分光总日射表校准因子的迭代计算法。
